By the time they found Martha, the group had changed the plans. At first, they planned to attack and distract the group in order to flee. But when the dracanae transformed and now had a form closer to lesser dragons, Martha had to change it again.
Martha had to increase the time to distract them while they fled. And to do that, she needed to have the capability to walk. There was also the issue of the nearby dracanae ghouls that were wandering around the area.
Hunter, Hems, and Hemsey had repositioned themselves for this battle. There were many preparations that they had to do in those short minutes.
The first one was killing all the ghouls nearby. They couldn't afford any more distractions for the planned escape.
